To aZZ whom it may concern:

Be it known that I, Jenn F. OComron, a citize n of the United States, residing at Chica o, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Side Bearings, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part ofthis specification.

This invention relates to improvements in side bearings.

One object of the invention is to provide a side bearing particularly adapted for railway cars wherein the anti-friction element is automatically centered under the influence of gravity after each actuation and upon removal of the 3ressure.-

More speci cally, the object of my invention is to provide a side bearing having gravity weights so arranged that, when the anti-friction element proper is moved to either side of central normal position, the gravity weights will be elevated and thereby moved to a position to automatically in sure the return of the anti-triction element when the load is removed. v

In the drawing, Figure 1 is a vertical, sectional view taken through the ends of a body and truck bolster of a car showing my improvements in connection therewith.

Fi ure 2 is a vertical sectional view corre spending substantially to the line of Figure 1. And Figure 3 is a top plan view 5 of the side bearing propershown in Fig ure 1.

In said drawing, indicates the upper portion of a truck bolster and ll the a1- dcrside of an opposed body bolster of a rail-'- vay carf. As shown, the improved-bearing is attached to the truck bolster and com prises, broadly, a retaining or housing castlng A; an anti-friction element proper B;

walls 1414, the casting being open atthe' top as clearly shown in Figures 1 and 2. The casting is provided with suitably perforated flanges 15 by. which the casting is adapted to be secured to the bolster, as by the rivets 16. Preferably, an inserted W1 through. openings in the side Walls 14 before the p plate 17 is employed in the bottom ofthe ouslng, said plate being inserted through suitable openings 18 in the end walls of the housing and secured in place by rivets 19,

the bottom of which are made flush with the lower surfaceof the housing 7 The anti-friction element B, as shown, is 111 the form 0]": a cylindrical roller and is centrally perforated to accommodate the retaining pin D which is loosely passed there- Said pin D is applied through 14c andpreveuting the roller from being lifted out. Said pin also extends through recesses in the weight blocks C so that the latter are'also retained, as will be obvious.

The weight blocks C are of like con-- struction, the same being located one at each end of the roller B. Each of said weight blocks C is in the form of a relatively thicl; plate of rectangular outline and of such a height that, normally, theupper edge 22 thereof is disposed below the upper edge of the housing and said edge 22 when the weight blocks are in their most elevated position, will always be below the upper contacting portion oi the roller. Each weight block C is provided with an elongated recess :23, having a lower edge defined by an arcuate convex surface 24, curved end surfaces 25?25 and an upper edge defined by two end flat surfaces 26- 26-, and two intermediate flat surfaces 27.-27. The flat surfaces 27 are inclinedupwardly from the horizontal at comparatively acute angle with the horizontal, whereas the other two surfacesfifi are inclined upward-- ly at a much greater angle with respect to the horizontal. Each set of surfaces 26 and 27 intersect or merge at a point, as indicated approximately at 28. It will alsobe noted from an inspection of Figures 1 and 3 that the weight blocks C are restrained from longitudinal novenient with respect to the housing A, or, stated in another manner, are confined to a vertical movement only. The edges of the weight blocks C may be cut away as indicated at2'9, near their centers to permit foreign matter to be hand little rollers 8n will travel in a down Washed outfrom within the housing, the side walls of the latter being similarly apertured as indicated at 30.

The roller B carries two diametrically disposed pins 31 and 32, said pins being in horizontal alinement when the roller is in its central normal position shown in Figure 1. The ends of said pins 31 and are projected beyond the ends of the roller and each projecting end of each pin 31 and 32 carries an anti-friction little roller. 31 and EL, respectively. Said little anti-friction rollers 31 and 39- are disposed within the recesses 23 of the weight blocks'C and, in normal position of the parts, will engage the upper edges of said recesses approximately at the points 28, as shown in Figure 1 so that, when the weight blocks C are in their lowermost POSltlOlh iillB roller will be thereby held in central position. 1 hen the roller is actuated to either side of central position,

as for instance, toward the left as shown by the dotted lines in Figure 1, the two leftward direction to the position indicated by the dotted lines 32 while at the same time the other little anti=friction rollers 81' will be elevated until they reach the position shown by 31 in Figure 1. The elevation of the rollers 31 results in a corresponding elevation of the weight blocks C which, as heretot'ore stated, are confined to a vertical movement. Consequently, when the load is taken from the anti-friction roller, the weight blocks C will automatically bear down upon the little anti-friction rollers 31, causing the latter to induce a return rolling action of the anti-friction roller, until the parts again assume their central. position.

In this connection it will be observed that, in returning the anti-friction roller to central position, there is no danger of overthrow since both sets of anti-friction rollers 31 and 82 will be engaged with the weight blocks C at points equidistant from the center thereof.

All of the parts are held in assembled relation in the manner heretofore described and from the preceding description, it will be seen that I insure automatic return of the antifriction element to central position;

The arwith a retaining member adapted to be secured to a bolster; of an anti-friction element adapted to roll back and forth with in said retaining member; weight block mounted in said retaining member'and confined substantially to a movement at right angles to the line of bodily movement of the anti-friction element; and co-operating means on said anti-friction element and weight blocks to effect elevation of the latter when the anti-friction element either side of central position, said weight blocks being then effective to return said element to central position when one load is removed.

2. In a side bearing, the combination with hollow housing adapted to be secured to a bolster; or an anti-friction element adapt ed to roll back and forth within said housing; a weight block mounted within said housing and guided by the latter in a vertical direction; and co-operating means on said roller and block automatically operable to elevate said block when the element is rolled to either side of central position.

In a side bearing, the combination with a hollow housing aoapted to be secured to a bolster; of an anti-friction element disposed within said housing and adapted to roll back and forth therein; of a pair ot weight blocks, one at each end of said r0] er and interposed between the ends of the latter and walls or" the housing, said weight blocks being confined to a vertical movement with respect to the housing; and co operating means on said elemmt and weight blocks for effecting elevation of the latter when said element is rolled to either side of central position.

4.111 a side bearingy the combination with a hollow housing adapted to be secured to a bolster; of'an anti-friction element disposed within said housing and adapted to roll back and forth therein; or a pair of weight blocks, one ateach end of said roller and interposed between the ends of the latter and walls of the housing, said weight blocks being confined to avertical movement with respect to the housing and co-operating means on said element and weight blocks for efi'ecting elevation oi? the latter when said element is rolled to either side of central posit-ion, said meansincluding eccentrically disposed'projections "from the ends of the roller and recesses within the blocks within which said projections are is moved to tially to a vertical movement with respect to the housing, each of said blocks having an elongnated recess therein; and diametrically disposed projections from the ends of said roller and disposed within said recesses and by which the weight blocks are elevated when the roller moves to either side of central position.

6. In a side bearing, the combination with a hollow box-like housing adapted to be secured to a truck bolster; of an antifriction roller mounted within said housing and adapted to roll back and forth therein; a pair of weight blocks, one at each end of the roller and interposed between the ends of the latter and side walls of the housing, each of said blocks having an elongated recess therein; and diametrically and eccentrically disposed projections at each end of the roller disposed Within said recesses and normally engaging the upper edges of said recesses whereby, when the roller is moved to either side of central position, the blocks are elevated in a vertical direction and automatically serve to return the roller to central normal position when the load is removed. I

7. In a side bearing, the combination with a housing adapted to be secured to a bolster, said housing having side walls; of an antifriction roller adapted to roll back and forth within said housing; a pair of weight 'blocks, one at each end of the roller and inconfining movement of said weight blocks-- to a vertical direction with respect to the housing; and diametrically and eccentrically disposed smaller anti-friction rollers car- 40 ried by each end of said first named antifriction roller, said smaller anti-friction rollers working within said recesses of the weight blocks.

8. In a side bearing, the combination with a casing; of a counter-weighted roller mounted therein; and a vertically sliding weight coacting with said roller to effect return of the latter to normal position.

9. In a side bearing, the combination with a casing; of a roller within said casing; a sliding counter-weight within said casing guided for vertical movement only; and coacting means on said roller and weight for maintaining a predetermined relation 65 between said roller and casing.

10. In a side bearing, the combination with a casing; of a roller within said casing, said roller being provided with eccentric lugs; of a pair of sliding counter-weights within said casing, said counter-weights being provided with guideways for receiving said lugs; and means for guiding the counter-weights for movementin a predetermined path.

In witness that I claim the foregoing I have hereunto subscribed my name this 6th day of July 1923.
